IMPROVEMENT IN SKY-LIGHTS.

The Schedule refari'ed'to izx these Letters Patent and making part of the same. 4-

To'all whom it may concern Be it known that I, GEORGE HAYES, pt the city,

a county, and Stateof New York, have invented a new;

and useful'lmprovement in Sky-lights, applicable to conservatory and other glazedroofs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, and in which- Figure 1 represents a vertical section of the onehalf of a conservatory roof constructed according to my improvement;

Figure 2, a section taken in a crosswise direction to fig. 1, through the line a; z; and

Figure 3, a front or side view of an end 'clip at foot of the roof, detached. I

Similar letters of reference indicate corresponding parts.

My improvement relates to metal sky-lights or glazed roofs, and has for its objectlightness combined with strength, as well as to efi'ectually provide against leakage, and the drifting of snow into or beneath the structure.

Said improvement comprises a novel arrangement of stay-plate in the hollow metallic rafters of said structure, whereby great strength is secured without a adding materially to the weight of the rafter.

Also, the improvement includes a novel construction of end clip, and indirect arrangement of escapeopenings from the main gutters, to provide for'the escape of water and prevent snow from beating in,

also contributing to strength.

Referring to the accompanying drawing- A A represent the hollow metallic rafters of the sky-light or roof, varying in length, size, and number, according to the area designed to be covered by the structure, and serving, in connection withcross-bcams or transoms, to form a main frame.

' As applied to ac'onservatory roof, said rafters run from the ventilator B to the wooden curbing.

These rafters,'as in another style of rafter described .in an application which I have made for Letters Pat- .ent of the United States,'arc each composed of .a

sheet-metal body, a, bent to form rebates b b for support of the panes or sheets of glass 0, along their sides or edges, and gutters c c, forthe escape oi water heating or leaking into the structure; also, formed with a lower Vor other suitably shaped sheet-metal molding, (I, bent at its upper edges to overlap and clip the upper edges of the gutters c 0, but the rafter hereshowu difl'ers from that described in a previous application, to which I have referred, in the introduction of a vertical sheet-metal stay-plate, 0, arranged to extend from top to bottom of the rafter, including its molding d, and which, as thus arranged, serves materially to stiffen the rafter without materially adding to its weight, and that, by slightly increasing the thickness of, will give much additional strength to the rafter, with the same thickness of sbell or body to the latter.

The glass 0, which is slid along the rebates b b, is protected or covered at its edges by sheet-metal caps, which, as shown at D, may be of saddle or inverted U-shape, to better brace or stiifen the upper joint of the rafter that it is seated on and suit-ably secured to.

the lower hollow transom, and finally to pass off by apertures g, made intermediately of the latter in the front thereof, and in the end clip G at the foot of the roof, which arrangement effectually provides against tbe'beating in of snow to produce leakage.

The outlets ff may be covered by strainers, if desired.

The end clip G is made of angular form in its transverse section, to cover the lower edge of the glass, and to overlap the front face of the lower transom E.

Thus made and arranged, it prevents snow or rain driving in under the lower edge of the glass, and said clip is formed with corrugations, h h, in it, which not only give strength to the clip, but constitute gutters for water to run off from the glass.

What is here claimed, and desired to be secured by Letters Patent, is-'- 1. The arrangement of tlierei-tical stay-plate e, r
